Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!

Try this experiment to give your curious kid a more "solid" understanding of how temperature affects the states of matter.

Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

What's a liquid? What's a solid? What better way to experiment than by turning a childhood favorite, ice cream, into a homemade science lesson!

First grade science often covers solids, liquids, and gases. This silly science explores serious facts about the difference between all three.

Satisfy your sweet tooth with this easy summer activity! Make homemade ice cream and let your child practice his science skills.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.
